Queen + Bowie: Name of 3 unreleased tracks

You can imagine how difficult those sessions might have been between all of the various personalities involved.

Those three titles are not Queen/Bowie songs – they’re other artists’ songs that sample Under Pressure.

I seem to recall maybe Peter Hince saying they jammed to All the Young Dudes, which makes sense.

As an aside, I Feel Free would've been interesting as the Queen guys would've seen Bowie and The Spiders playing it live when they saw him in early 1972.

As you see below, Mott would be good candidates to jam as both Queen and Bowie share history with them and Cream were a mutual interest. There's a bootleg of outtakes from the Mott's All The Young Dudes album sessions jamming stuff like Shakin' All Over with Lou Reed so it's not unthinkable these guys just get together and play whatever is on their mind that particular day.

1980-82 were weird years for Bowie. Having delivered his final LP for RCA and untoured since 1978, he was in a strange hinterland of reissues and stand alone singles as he counted down his RCA contract before moving on to EMI with 1983's Let's Dance. Away from music and concentrating on acting, I think he would've been interested in letting off steam playing anything with a band with no strings attached as he had always done. The life of a solo artist is very different to a band - despite having regular musicians, he was able to pick who he wanted for different projects, be it try outs or just mucking around. Only in 1977 he'd toured as Iggy Pop's keyboard player. There's a famous picture of him on sax during a jam at Peter Seller's house in 1975:

"He ran through a few blues numbers with an impromptu group called Trading Faces. Comprising: Bowie (saxophone), Bill Wyman (bass), Ron Wood (guitar), Joe Cocker (vocals), Jesse Ed Davis (guitar), Danny Kortchmar (guitar), Bobby Keys (saxophone) Nigel Olsson (drums), Keith Moon (organ, vocal, drums) and Steve Madaio (trumpet)."

He would be happy to do old Bowie songs - see a session in December 1979 which he threw together some self covers (Panic In Detroit, Space Oddity and apparently Rebel Rebel) and performed various TV shows (SNL, Johnny Carson, Dick Clark’s Salute To The Seventies) with thrown together backing bands. I doubt Freddie or Brian would have resisted playing a few Bowie intros and I can picture Bowie correcting them or telling a story about how Ronson nailed that solo as he knew they were at heart, fanboys. 

There was an article in The Guardian from 2017:

Hince knew Bowie well, having worked as one of his roadies “in the Ziggy and Diamond Dogs days
“They just started knocking things around. They did cover versions [and] a few of their own things"
The revelation will be published in a forthcoming book on Bowie by Neil Cossar, a music historian. In one passage, Hince recalls: “They … performed some original songs they did together and also covers. They were just jamming in the studio and it all got recorded – All the Young Dudes, All the Way from Memphis and various rock classics.”
Speaking to the Guardian on Wednesday, Hince said there was no question that the recordings exist.
Hince said of the unreleased recordings: “There’s stuff with Freddie and David singing together – proper full-length rock’n’roll tracks … Raw, but good.”

And again in 2021:

A new conversation with Taylor and Brian May in a special one-shot edition of Record Collector dedicated to Queen reveals that further recordings exist from those sessions, including covers of songs by Cream.
“If we look to the archives, yeah, there’s probably stuff,” says Taylor. “We would do the odd thing like covering old Cream songs. I remember we did NSU and I Feel Free, just for a laugh really, and then we decided, ‘Let’s write one for ourselves.’”

EDIT: Worth noting too that Bowie actually had a studio crack at I Feel Free as recently 1980 during the Scary Monsters album - an instrumental has turned up on bootlegs entitled 'Is There Life After Marriage'
